Where did my mapped drives go?

Application:
RPGILE launches VB6 application.  VB6 Application uses a DriveListBox to 
display all available drives.

Configuration:
Windows XP Professional,
Network Domain Server,
User Signon to Domain and iSeries are different,
Visual Basic 6,

User Signon:
        iSeries 400 and PC/Network signons are different. 
            Therefore the Windows "Run As" is used to activate the iSeries 
400 user signon and access to the IFS.

Actual Drivers are:
        C:\     [local drive]
        D:\     [CD drive]
        F:\     [local drive]
        M:\     [Mapped drive \\iSeries_systemname\sharename1 
        P:\     [Mapped drive \\iSeries_systemname\sharename2 

Problem: 
When the VB6 application is lunched using Microsoftâs RunAs.exe.  The 
DriveListBox does not see any of the Mapped iSeries drives. 
Drives displayed in DriveListBox:
        C:\     [local drive]
        D:\     [CD drive]
        F:\     [local drive]
 
        The DriveListBox does not recognize M:\ or P:\
        However, if the path (\\iSeries_systemname\sharename1) is used the 
application instead of M:\,  access the desired object is achieved.
        Using the DriveListBox and DirListBox makes if easier and more 
user friendly to select the desired object.

How can I make the Mapped iSeries drive recognized. 

By the way,  this all works when the OS is Windows 2000.
